I To all whom tam/my concern:

Be it known that I, CHARLEs P. McMnLnnN,

'a citizen of the United States, residing in the borough of- Brooklyn, city of New York, county of Kings, and State of New York, have invented certain new and useful Improve:

ernors may be kept thoroughly lubricated at all times, a further object being to-,provide an lmprovement of the class referred to for engines or apparatus of the class specified designed for use in buildings, steamers,. and other vessels for pumping water intoiand through stand-pipes and other connections; and with invention combination, and of parts hereinafter-described consists in the construction, and claimed.

The invention is fully disclosed in the following specification, of which the accompany part, in which the separate parts of my improvement are designated characters in each of the views, and in which Figure 1 is a sectional side view of a pumping-engine and its connections provided with my. improved governor; Fig. 2, a section on the line 2'2 of Fig. 1; Fig. 3', a bottom plan view of a detail of the construction shown in Figs. 1. and 2; Fig. 4, a section on the line L 4 of Fig. 2; Fig. 5, a sectional side elevation showing a modification of the construction Fig. 6 a sectional side elevation of apart of the construction shown in Fig. 1 and showing an oiling device connected therewith. I

In the drawings forming part of this specification I have shown ata an ordinary pumpingengine with which is-connected a water-supply i pipe a this connection being made in theordinary manner, and conn the cylinder 6 -with which said 'movable cross-head c, shaped frame.

. the tension of, the

having branch connections a, with which in nected in the usual manner;

. Inv thev practice of my iuventionIfconnect with the lead-pipe a a three-way coupling 6, with'which is'connected a piston-cylinderb", having a headpractice Jordinary hose may be con member 6; with which iscounected a yoke-shaped frameb, andplaeed in the cylinder 6 which passes upwardly through the head 6 of and through a 'stufiing bo'x 6, head is provided, and through the head b.of the yoke-shaped frame 6. piston-rod c also'p'asses through a'verticallymounted in the yoke- 6, and the rod 0 where it is passed through the cross-head c is screwis a piston '0, having a rod '0 t The threaded, and by means of this construction the position of said cross-head on said rod may be regulated or adjusted vertically. The rod 0 is also provided above the cross-head a with a nut 0 between which and .the head I) of the yoke-shaped frame 6" 0 and the nut c is vertically adjustable on the rod 0 and by means of this construction spring '0 may be regulated. Mounted on, the cross-head b of the yokeshaped frame I) is a cap 0?, which is secured to the cross head by means of screws or bolts passed through holes LP, and said cap isprovided with side flanges d, which hold the spring 0 in proper position. view of the cap d is given in plan of the cross-head a and yoke-shaped frame 6 is given in Fig. 4.

Connected with ,the pump a is a steam-supply pipee, which may receive any suitable source, and placed A bottom plan section of the tlon shown in Fig. 1 the throttle-valve i'sop-. erated by the rod e, the, upper end of which f. The valve or is connected with a lever valve-casing 6' is provided at its opposite sides with supports f",

is placed a spring Fig. 3, and a" to; one of. which the steam from I in this pipe IS a throttle-valve c of. the ordinaryconstruclever f is pivoted, andlthe shorter end'of the lever f is movable in avertical slot f,

. formed in the other support f and the longer tomatic at all times.

in the pipe a is lowered beyond' the said pre-' end of said lever is connected with the upper end of the piston-rod c as shown at f, and. said lever is also provided with an adjustable weight f The pump a is provided with an exhaustpipe f, and theoperation of this construction, as shown in Figs. 1 to 4, inclusive, is as follows: It will be understood that the ten sion of the spring may be regulated to any desired extent, andtlie weight f may also be adjusted so as to aid in regulating the pressure on the piston-rod c andwhen the pump a is put in operation the water will be forced through the lead pipe-a into the stands pipe a and into the branch pipes a in the usual manner., If at any time the pressure in the pipe a reaches or ,exceeds apredeten mined amount. the pistonc will be operated and the throttle-valve 6 will he closed and the steam-supply to the pump will be cut off,

and this action, as will be understood, is au- As, soon as the pressure determined point the operation of thepiston .0 will be reversed and the steam will again pass through the throttle-valve e and the operation of the pump will be renewed. It will also be apparent that the flow of water from one or" more of the branch pipes a? Will lessen the pressure in the pipe a and the pump a will be operated with greater force, and the closing of one or more of the pipes a will reverse this operation, the pressure in the pipe a will be increased, and the piston a will be operated and the supply of steam to the pump will be cut OH, and the operation of the pump is thus made automatic.

The head 6 of the cylinder Wis provided. with a by-pass g, having a drain-pipe 9 the'.

object of. which is to allow any water that may pass around the piston c and collect in the upper end of the cylinder Z2 to flow out or drain out, and thus be prevent d fiom being forced through the stuifing-h x6 y In Fig. 61 have shown a modification, or rather a means for oiling the cylinder h which is particularlydesigned for use in caseswhere' salt water is pumped through the pipes a, a

intermediate coupling member gisan oil-cup 9 this connection being made by means ofa pipe 9 and in practice whenever it is desired to oil the cylinder For the piston a the valve 9* is closed and any waterinathe cylinder 6 is allowed to drain ofl? through-the drain-fan -cet g Oil is 'then allowedfito flow into the coupling memberlgr and cylinder '6, and inv Fig. 6 this oil is shown-at k as resting on the .water b and in this way the'cylinderjb and the piston 0 may be thoroughly lubricated at any and all times or whenever necessary.

In Fig. 5 Ihav e shown a modification of the construction-shown in Fig 1, in which the throttl'e valve e isplaced directly-over the" cylinder biflud'the valve-rod e is connected directly-with the upper end of thepistoxi-rod 0 as shown-atE/z, and iinthis form of construction theflvalve-rod c passes-vertically through the casing of the throttle-valve and is vertically movable therein, and the upper end .thereof is provided with a pluralityof weights-l2. Inthis form of construction the spring '0 operates in thesame manner as with" the construetiomshown in Fig; 1', and the Y weights it take the place of the weight f and the pressure of water necessary to operate the piston 0 may thus be regulated.

Although I have shown anddscribe d jiny improvement for oiling or lubricating the cyllj inder of a particular form of governor for pumping-engines designed for pumping water through'istand-pipes and other connections,

in buildings, steamers, and other vessels, it,

will be apparent that the same may be usedin connection with governors for such engines of any desired construction, but which empl'oy a cylinder and a piston movable therein, the engine being under the controlfof'said piston, and I reserve the right to make all .IOO;

suchalterations in the construction herein shown and described as fairlycome within the scope of the invention;
